Alright, let's speak hypothetically here.
Let's say that I want to take my current position and the position of another person and then find the distance between us. I am aware of the formula to find the distance between two points, however I would like to know how I would go about doing it in Blockland. The reason for my wanting to know this shall remain unknown to anyone but myself for the time being.
I greatly appreciate all, if any, help.
